To all whom it may concern,.-

Beit known that I, WILLIAM DEWEY, a citizen of the United States,residing at Thorp, in the county of Clark and State of Wisconsin, haveinvented a new and useful Whiftletree- Hook, of which the following is aspecification.

The invention relates to improvements in whiiiietree hooks. X,

The object of thepresent invention is toimprove the construction of"whiffletree hooks, and to provide a simple and inexpensive one whichwill be positive and reliable in its operation, and which will securelyhold a trace when locked and will enable the same to be quickly detachedwhen desired.

' The invention consists in the construction responding parts in theseveral figures of the drawings.

1 designates a rigid hook, adapted to receive the eye'of a trace, andprovided with an integral ferrule or sleeve 2, adapted to be placed onan end of a whiflietree, and provided adjacent to the arm 1 with anannular shoulder 3, forming a bearing for a spring 4, that engages asleeve 5, having an arm 6, which co operates with the arm l. The sleeve5 is rotatably mounted on the ferrule 2; it covers and conceals thespiral spring 4, and is provided with an inner annular shoulder '7,forming a bearing for therother end of the said spiral spring 4, wherebythe shoulder and the sleeve 5 are forced inward with relation to thewhiftletree. Thel sleeve 5 is retained on s the ferrule 2 by an annularflange 8, itted on the end of the ferrule 2 and consisting, preferably,of a collar, and secured on the said ferrule by swaging the end 9thereof, or by any other suitable means. L-shaped, has its branch, whichis arranged parallel with the whiietree and which re- The arm 1, whichis receive the outer end 1l of the arm 6 of the sleeve; the outer end 1lof the arm 6 1s reduced and is introduced into the recess 10 throughavnarrow slot or entrance-opening 12, and it is forced away from theentranceceivesthe trace, provided with a recess 10, to

slot or opening by the spiral spring, and is Iirmly retained inengagement with the arm 1 at the outer end of the recess 10.

:When it is desired to detach the trace, the

sleeve 5 is moved inward on the ferruie against the action of the spiralspring until the reduced end 11 of the arm 6 is opposite 'the entranceslot or opening 12, and the sleeve 5 is then rotated, partially, tocarry the reduced endll outward through the entrance slotor vopening 12to separate th'e arms 6 and 1. The trace may then be removed from orplaced on the arm 1, asv will readily be seen.

It will be apparent that the arm l, whlchls L-shaped, is rigid and formsa firm and secure support for the trace, which is not connected orattached by any movable part that is liable to work loose or becomedetached by the vibrations f the trace. It will also be seen that thewhiftletree hook is simple and com,-

' paratively inexpensive in construction, that it is adapted to bereadily applied to any ordinary singletree, and that it is capable ofsecurely holding a trace, and of enabling the latter to be quicklydetached when desired.

Changes in the form, proportion, and the minor details of constructionmay be resorted to without departing from the principle or sacrificingany of the advantages of this invention.

1. In a whiflietree hook, the combination of adapted tobe placed on theend of a whiflietree, a -rotary sleeve mounted on the ferrule andprovided with an arm interlocking with that of the lferrule, said rotarysleeve having a sliding movement longitudinally of the sleeve or ferruleto disengage it from the arm thereof and a spring arranged beneath therotary sleeve and concealed bythe same and adapted to hold said armsk inengagement, substantially as described. s

2. A whiflietree hook comprising a hookarm provided with a ferrulehaving an annular shoulder, a rotary sleeve mounted on the a hook-armprovided with a sleeve or ferrnle" ferrule and having ou its interior anannular shoulder and provided with an outward projecting arm arranged tointerlock with that of the ferrule, and a spiral spring disposed on theferrule and engaging said shoulders, whereby the arms are heldinterlocked, suby stantially as described. y

3. A whifletree hook comprising a ferrule adapted to be placed on awhifetree, a hooked arm rigid with the ferrule and provided at its outerterminus with a recess and having an entrance-slot communicating withthe recess, a rotary sleeve mounted on the ferrule and provided with anoutward-extendin g arm having its outer 'extremity of va s .ize to enterthe I5 said entrance-slot to engage the recess, and a spiral springdisposed on the ferrule and engaging the rotary sleeve, whereby the armof the sleeveis held in engagement with the recess, substantially asdescribed. 2o

In testimony that I claim the foregoing as my own I have hereto aixed mysignature in the presence of vtwo witnesses.

WILLIAM DEWEY.
